- New translate() function.
- Added example figures
STAM Transpose
- Minor rephrasing

v1.2.0 - 2025-07-18

STAM Core
- Added Map type for data values. Arbitrary nested maps are now supported but should NOT be used as a substitute for annotations on annotations #34
- Removed the constraint "Any String value that is a valid IRI SHOULD be interpreted as such in conversion from/to RDF", actual interpretation of IRIs vs string literals can now be delegated to the JSON-LD context.
STAM Query Language
- Added a . operator to get keys from maps (note that as an operator in STAMQL, is requires whitespace both left an right)
STAM Web Annotations
- Hierarchical structures can be mapped used the new Map type. Web Annotation targets and selectors that have no counterpart in STAM can now be encoded in this way.
- JSON-LD context determines interpretation of IRIs vs string literals. The specification now makes clear how you can link to external resources using IRIs.
STAM Translate
- This is a minor new extension used to relate any texts, even if the text are not identical. It is a more generic and more limited form of the STAM transpositions.

Stricter definition of relative paths in @include mechanism, don't leave it to the implementation.
